All centuries completed during the year count, whether they're official
club centuries, solo rides, or big-event centuries. Any century listed in
the club calendar counts as an official club century, even when there is
more than one in a given month. Doubles count as two centuries.
While the goal is 100 miles, we will accept rides that are close but perhaps
two or three miles short, especially if the ride in question is very
difficult. It's an honor system: if you're comfortable listing it, that's
all that matters.
